# List Google Tasks Goal: fetch tasks from the **default account's default task list** via `gog tasks list`, filter by what the conversation asks for, and present them. The skill ends at presentation — what happens next (planning a flow, prioritizing, completing tasks) is ordinary conversation, not this skill. This skill is **read-only, enforced by mechanism**: every call carries `--readonly`, which makes gog reject mutating API requests at runtime. Adding is `add-google-task`; completing, editing, and deleting are out of scope — use `gog tasks` subcommands directly (with the user's explicit go-ahead) when that need arises. ## Identity stays out of the repo - The task list argument is always `@default`, and `-a` / `--account` is never passed. - "Whose tasks" is resolved by the machine-local gog state (Keychain). Never hardcode an email address, list name, or list ID. ## Workflow ### 0) Preconditions `command -v gog` and `gog auth status` must both succeed. If gog is missing or unauthenticated, point the user to the setup path and stop: ```bash gog auth credentials # one-time client setup gog auth add # add an account ``` ### 1) Derive the filter from context (don't interrogate) The trigger is typically terse — "今日の task なに？". Map the utterance to flags instead of asking: - **Due window** — resolve relative expressions (今日, this week, 明日まで) against the system clock. Google Tasks stores due dates as **date-only, midnight UTC** (`YYYY-MM-DDT00:00:00.
